context_page_description: This list of birds of Oklahoma includes species documented in the U.S. state of Oklahoma and accepted by the Oklahoma Ornithological Society's Bird Records Committee. As of October 2017, there were 480 species on the official list. Between then and July 2020, four additional species have been documented in eBird. Of the 484 species, 110 are classified as accidental, seven have been introduced to North America, two are known to be extinct, and two others might be extinct. An additional 16 species are classed as either hypothetical or of uncertain origin; 13 of them are also classed as accidental.
  This list is presented in the taxonomic sequence of the Check-list of North and Middle American Birds, 7th edition through the 61st Supplement, published by the American Ornithological Society. Common and scientific names are also those of the Check-list, except that the common names of families are from the Clements taxonomy because the AOS list does not include them.
  Unless otherwise noted, all species listed below are considered to occur regularly in Oklahoma as permanent residents, summer or winter visitors, or migrants. These tags are used to annotate some species:
